libmpq is a library for manipulating MPQ (MoPaQ) archives, which are used by Blizzard in most of their games (e.g., Diablo, Diablo 2, StarCraft, WarCraft 3, and World of Warcraft).

Currently the shared library name is created according to version from configure.ac which is simply wrong. Modifiy the source to follow http://nondot.org/sabre/Mirrored/libtool-2.1a/libtool_6.html#SEC36
Reading from the archive in multiple threads is not thread-safe. It'd be great if the library provided a way to duplicate an existing mpq_archive_s so that thread-safe reads are possible without locks.
Newer versions of World of Warcraft (Wraith of the Lich King and Cataclysm) are using modern version of MPQ format. We need to support them as well.
StarCraft II Wings of Liberty is using LZMA beside BZIP2, ZLIB and PKWARE. We must support it for handling those archives.
File Sfx\Items\Titlemov.wav in DIABDAT.MPQ from Diablo 1 is read incorrectly with this library.

Upon inspecting, I can see that the file is encrypted but not compressed (flags are 0x80010000).
This means libmpq__decrypt_key is never called, so the decryption seed then ends up being 0.
According to StormLib, the correct key here is 2227372475.
Looks like StormLib generates the decryption key from the filename (although it does also have a heuristic to decrypt WAV files).
There should be a way to do something similar here as well.
The library appears to read the 16-bit and 32-bit ints directly into structs via fread without byte-swapping them on big-endian platforms.
Hi, to provide some context on the barrage of PRs: I want to replace StormLib in DevilutionX, a Diablo 1 source port, with libmpq.
To that end, I needed to make a number of fixes/enhancements to libmpq, all of which are here https://github.com/diasurgical/libmpq/
I'm simply upstreaming them piecemeal
It'd be very useful to have a streaming API for files with read/seek functions, so that it can be wrapped as e.g. SDL_RWops for audio streaming.
Remove the *block_open_offset() and *block_close_offset() public functions, effectively everybody should use *block_read() only for block processing and this function should handle low-level block processing itself.
When looking up a file in multiple archives, it'd be useful to avoid recalculating the hash multiple times.
